JOSEPH CB. ROCHELLE, OF NEW ORLEANS,

LOUISIANA, ASSIGNOB T BOROTHI RE- FRIGEBATING MACHINE 00., INC., OF NEWORLEANS, LOUISIANA ICE MAKING Application filed July 11,

The device forming the subject matter of the application is a freezingapparatus or icemaking machine, and one object of the invention is toprovide novel means whereby the la brine is forced, by the action-of apump, to

to provide novel means for mounting the drop pipe and attendant parts onthe ice can.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the presentinvention appertains.

With the above and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of of construction hereinafterdescribed and claimed, it being understood that changes may be made inthe precise embodiment of the invention herein disclosed, within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings:

Figure 1 shows in horizontal section, a device constructed in accordancewith the invention, most parts appearing in top plan, and the cover forthe tank having been removed;

Figure 2 is a vertical section;

Figure 3 is'a top plan of one of the ice cans;

Figure 4 is a section of the ice can; v

Figure5 is a vertical section of the ice can and parts within it;

Figure 6 is an elevation of the ventilating mechanism for the brinetank.

The numeral 1 marks a brine tank including a cover 2, part of which isremovable. Referring to Figure 6 of the drawings, the brine tank 1 isventilated through a stack 3 on the cover 2, the fumes passing from thetank into the stack 3 through a pipe 4 in which a valve 5 is interposed.

- A hollow pedestal 6 is mounted on the cover 2 of the brine tank 1, anda vertical vent pipe 7 communicates with the pedestal 6. A lateral pipe8 communicates with the pedestal 6. 'The inner end of the lateral pipeAPPARATUS 1930. Serial No. 467,307.

8 is upwardly inclined and terminates in a substantially vertical nozzle9 located within the stack 3. The numeral 10 marks a horizontal airinlet which is mounted at 11 on the upper end of the vent pipe 7, toswing horizontally. A vane 12 is secured to the funnel 10 and keeps thefunnel headed into the wind. Air moves through the funnel 10, throughthe pipe 7, through the pipe 8, and through the nozzle 9, air beingdischarged into the stack 3, to aid in carrying the fumes out of thebrine tank 1, through the pipe 4 and the stack 3.

An inlet header 14 extends crosswise of the brine tank 1, at one endthereof. A U-shaped pipe 15, shown in Figure 1, connects one end of theheader 14 with the brine tank 1. In the pipe 15, a combined suction andforce pump 16 is interposed.

That end of the .inlet header 14 which is remote from the pipe 15 isconnected to a water inlet pipe 17 provided with a valve 18 under thecontrol of an operator. The water inlet pipe 17 is used for washing outthe brine line, when the valve 18 is opened, also by circulating steamfrom the pipe 17 through the brine line the drop line may be ilhawed outfacilitating removal of the center An air inlet pipe 19 is connected tothe header 14, a valve 20 under the control of an operator, beinginterposed in the air inlet pipe 19. The air inlet pipe 19 is used, whenthe valve 20 is opened, for blowing out the brine from the brine lineback into the tank 1.

An outlet header 21 extends across thev brine tank 1, at that end of thebrine tank which is remote from the inlet header 14. The outlet header21 is connected at one end, by a U-shaped pipe 22, to the brine tank 1.The U-shaped return pipe 22 carries a valve 23, under the control of anoperator. The numeral 24 designates an outlet, connected to the pipe 22,a valve 25, under the control of an operator, being interposed in thepipe 24. The valve 25 is opened in order to enable the brine system tobe washed out through the pipe 24.

A first pipe 26 is joined at one end to the one end of the tank. The pie 26 is closed at its end adjacent to the eader 21, as shown inFigure 1. In the p1 e 26- there is a valve under the control 0 anoperator, and disposed adjacent to the header 14.

Another first pipe 28 extends along that side of the brine tank 1 which1s remote from the pi e 26. The pipe 28 is in commumcation with theoutlet header 21. The plpe 28 is closed at 29, adjacent to the inletheader 14. A valve 32, under the control of an operator, is inte osed inthe pipe 28 and is dis osed near to t e outlet header 21.

second ipe 30 is disposed between the pipes 28 and 26 and is joined atone end to the outlet manifold 21. The opposlte end of the pi 30 isclosed, as shown at 31. There is a vs vs 34 in the pipe 30, near to theoutlet manifold 21. Underneath the pi e 34 is located another second ipe60. e pipe 60 is connected at one en to the inlet header 14. Theopposite end of the pipe 60 is closed as shown at 59. A valve 58, underthe control of an operator, is interposed in the pipe 60 and is disposedadjacent to the inlet header or manifold 14, as shown in Figure 2.

Referring to Figure 1, the machine is shown as containing two lines ofice cans 36, although there may be any number ofthese ice cans.Moreover, the ice cans 36 may be of an desired shape and size.

Refhrring especially to Figures 4 and 3, it will be seen that brac ets37 are mounted removably on the upper edges of the ice cans 36. At theirends, the brackets 37 have suspension elements 38, engaging the ice cans36 to support the brackets 37, and to prevent the brackets 37 from movinendwise.

Drop pipes 39 are mounte in the brackets 37, as shown at 40, by means ofclam nuts. The drop pipes 39 may be of any esired sha e, and there maybe as man or as few of t em, to each ice can 36, as t e operator wishes.The drop pipes 39 are closed at the bottom, as shown at 41. Each droppipe 39 has a top 42. Tubes 43 extend downwardly through the tops 42 ofthe drop pi es 39, and terminate a short distance from t e bottoms ofthe drop pipes, as shown in Figure 5.

Referring especially to Figure 1, it will be seen that pipes 44, whichmay be pieces of flexible hose, are detachably connected at 45 to theupper ends of the tubes 43. Pipes 46, which may be lengths of flexiblehose, are detachable connected to the pipe tops 42 of the drop pipes 49,and communicate with the drop p pes, near to the upper ends of the droppipes. The ipes 46 are detachably connected, or joine otherwise, to thepipe 30 which communicates with the outlet header 21. The foregoingdescription as to the pipes 44 and 46, relates especially to thelowermost of ice cans 36 in Figure 1.

4s to the uppermost line of ice cans 36 in this figure, these cansderive their supply of brine from the pipe that is joined to the inletheader 14', the brine entering the drop pipe through theipes 48, whichcorrespond to the pipes 44, t e brine leaving the drop pipes throughthe-pipes 49, which correspond to the pipes 46, the p1pes'49communicating with the pi e 28, which, in turn, commumcates with theoutlet header 21.

The brine is drawn by the pump 16 of Figure 1 from the tank 1 and isforced through the ipe 15 into the inlet header 14. From the inletheader 14, the brine moves into the pipe 26 and thence through the pi es44 into the tubes 43 of Figure 5, the brine eing discharged downwardlyon the bottoms of the drop pi cs 39. The brine moves upwardly in the roppipes 39 and finds an exit through the pipes 46, the pipe 30, and theoutlet header 21.

As to the u permost line of ice cans 36 in Fi re 1, the brine comes fromthe header 14 an moves along the pipe 60, the brine passing into thedrop pipes 39 through the pipes 48 and finding an exit by way of thepipes 49 and the pipes 28, into the header 21.

Referring to Figure 5, in connection with Figure 6, it will be obviousthat the pump 16 will force the brine downwardly through the tube 43upon the bottom 41 of the drop pipe 39, the br1ne fillin the drop pipeand passing out of the top of t e drop pipe. An unusual- 1y efiicientoperation results. Much time is saved in the operation of the machine.The structure may be used either for making ice or for freezing fruit,fish, and the like.

Having thus described the invention, what is claimed is:

1. In an ice-making machine, a tank, rows of ice cans in the tank, aninlet header ex tended transversely of the rows of cans and located atone end of the tank, an outlet header extended transversely of the rowsof cans and located at the opposite end of the tank in substantiallyparallel relation to the inlet header, first pi es located at the outersides of the rows 0 cans, each of the first pipes being closed at oneend, the opposite ends of the first pipes being connected, respectively,to the inlet header and to the outlet header, the first pipes beinarranged substantially at right angles to t e headers, second pipeslocated at the inner sides of the rows of cans in substantially parallelrelation to the first ipes,.each of the second pipes being close at oneend, the opposite ends of the second pipes being connected,

respectively, to the inlet header and to the.

outlet header, drop pipes in the ice cans, tubes in the drop pipes,connections between the first pipe that communicates with the outletheader, and the drop ipes of one row and connections between t e tubesof sai one row and the second ipe that communicates with the inletheader, connections b tween the second pipe that communicat with theoutlet header, and the drop pipes of the other row, and connectionsbetween the tubes of said other row and the second pipe thatcommunicates with the inlet header, all of said connections being shortdetachable, and located entirely at the tops 0% the cans.

2. In an ice making machine, an ice can, a bracket removably mounted onthe ice can, a drop pipe extended through the bracket and having aclosed top located above the bracket, clamps on the drop pipe andengaging the upper and lower surfaces of the bracket, a tube extendingdown into the drop pipe, through the said top of the dro pipe and indendentl of the bracket, an an outlet mem r for t e drop pi e, the outletmember being mounted in said top of the drop pipe, independently of thebracket.

In testimony that I claim the foregoing as my own, I have hereto aflixedm signature.
